AtDOF6, an Arabidopsis DOF transcription factor putatively involved in the regulation of seed germination

DOF proteins (DNA binding with One Finger) are transcription factors (TFs) that play diverse roles in gene regulation of plant-specific processes. In barley (Hordeum vulgare), 26 different DOFs have been described. Four of them (BPBF, SAD, HvDOF19 and HvDOF17) have been shown to play a role, not only in seed storage protein expression during seed maturation, but also in the regulation of hydrolase gene expression in the germinating aleurone cells.
